BAFFLE-WALL.

Application filed August 12, 1912.

State of New York, have invented certain new and useful Improvements in Batlle Walls, of which the following is a clear, full, and exact description.

This invention relates to an improvement in fire-walls preferably for steam boilers, the object being to provide such a wall that will withstand the action of the fire better than those now in use, said wall being of a simple construction and comparatively inexpensive.

My improvement will be fully set forth in the following specification, and the accompanying drawing, wherein- 1 Figure 1 is a diagrammatic side elevation, partly broken away, of a steam boiler embodying my improvement. Fig. 2 is anenlarged fragmentary sectional face view of a portion of my improved fire Wall. Fig. 3 is a sectional view of a portion of the fire wall, the section being taken on a line 3-3 in Fig. 2, showing the filling of refractory material. Fig. 4: is a similar view showing a further step in the forming of the wall; and Fig. 5 is adetail perspective view of one of the blocks which go to make up the wall.,

As herein embodied my improved fire-wall comprises a nest 1 of pipes indicated by 2, which at one end are connected together, as at 3, the other end of saidpipes being connected to a header or manifold 4. It is usual to form the flame plate of the firewallsof metal plates, which after a time buckle under the action of the intense heat; the buckling of the plates allows the brick portion of the wall to break down, and it is one of the objects of this invention to provide a water cooled backing for the fire wall that will not buckle.

A still further feature of my fire-wall comprises the diagonally disposed blocks of refractory material 8 which are'laid between the boiler'tubes 9 parallel one with' the other, and which serve as shelves or ledges to hold the refractory material or fireclay 10, as well as elements to aid in filling the spaces 12 between the tubes, to form a Wall for the deflection of the gases and flame from the fire on the; grate 11. As can be seen in Figs. 2 and 5, the blocks 8 are pro- Specification of Letters Patent.

vided with openings'13 for a purpose to be hereinafter described.

When the blocks 8 have been placed in position there will be provided. a pocket 14, the blocks 8 forming two of the walls of the pocket and the tubes 9 the other walls. One end of the pocket 14 will be crossed by the tubes 2 while the opposite end will be open, see Figs. 3 and' l. The final operation of forming the wall is to place in the pockets 14 the refractory material, such as a mixture of cinders and fire clay, the said mixture being applied whilein a plastic state. 'When the plastic material is stuffed into the pockets 14, some of the said material will flow into the openings 13 in the blocks 8, and when the material has hardened there will be a teat 15 projecting into the said openings, which will serve to hold the filling matter 10 in position in the pockets 14:. Any suitable means may be employed to stop up the openings in each end of the pockets 14 while being filled, and until the filling matter has hardened. After a little use ashes fromthe fire will collect as indicated by 16 in Fig. 1, which will still further insulate the wall. The pipes 2 not only act as an element of a flame plate, but they also serve as a backing for the blocks 8 and filling material 10. During the operation of the furnace water is circulated through the pipes 2 for the purpose of cooling the same.

In carrying out thisinvention, details of.

construction may be varied from those shown, and yet the essence of the invention be retained; some parts might be employed without others, and new features thereof might be combined with elements old in the art in diverse ways, although the heroin described type is regarded as embodying substantial improvements over such modifications.

As many changes could be made in the above construction, and many apparently widely different embodiments of the invention could he made without departing from the scope thereof, it is intended that all matter contained in the above description or shown in the accompanying drawings shall be interpreted in an illustrative and not in a limiting sense. It is furthermore desired to be understood that the language used in the following claims is intended to cover all the generic and specific features of the invention herein described, and all statements of the scope of the invention which as a matter of language might be said to fall therebetween.

.terial in the remainder of the space-between said tubes, a water cooled backing for said blocks and said filling material, comprising a plurality of tubes adapted for the circulation of water and headers for said tubes.

3. In combination with a nest of boiler tubes a firewall comprising a plurality of diagonally disposed blocks laid between said tubes to fill a portion of the space there- .between, a filling material in the remainder of the space between said tubes, and a water cooled backing for said blocks and said filling material.

4:. A boiler having a series of parallel rows of tubes, bricks forming shelves placed between the rows, the spaces between the tubes in a row or series being filled with fire clay between the shelves.
